Across the Corn Belt, mild, dry conditions are spreading eastward. Tuesday’s high temperatures will top 65°F in the southwestern Corn Belt, including parts of Missouri and Nebraska. The renewed warm weather is quickly eroding a patchy snow cover that had developed last week. Still, much of the upper Midwest is experiencing a “snow drought,” with season-to-date totals less than a foot—less than one-quarter of normal—being reported in locations such as Fargo, North Dakota (8.5 inches), and Sisseton, South Dakota (4.2 inches).
